Hey guys I have another question. Does the down pipe connect to the turbo? And also what is a good down pipe to get? I want one with a high flow cat on it. Thanks a bunch guys and sorry for all the questions I am a noob to all this. :?
you're running a turbo right??? what year vehicle??? pre '92 diesel doesn't require a cat
after that i'm not too certain, but most likely if the vehicle came with a cat, they will be checking for one come emissions time

You shouldn't be hearing a turbo at idle
You can if it's a VNT with closed vanes. :twisted: I have a 2.5" exhaust and a normal muffler BTW.

I have performed a mufflerectomy, and I must say it sounds beautiful. And I can hear my turbo while ideling...
And it sounds like a jet engine shutting down when I turn the car off. I am happy with the overall sound on the highway and street driving. I will post a video on youtube and post the link here. Thanks for the help guys!!

Let me ask you guys this, I like the sound of TDIs without a muffler and a bigger pipe and such. Does removing the muffler and such from a TD create the same effect? (Increase the turbo whistle?) Of course, a decent intake would be a must as well I suppose. So, what have you guys got a TD to sound like? Vids, sound clips?

I did a ghetto mufflerectomy to my 93 Jetta (actually the pipe after the cat broke off) and I still don't hear my turbo whistle unless I'm very close to the side of a building, then I can hear it a bit. I kinda like the exhaust sound, kinda sounds like a Honda with a fart can in a way. It's a bit too loud for my liking, if it were just a bit quieter it would be perfect. I'm thinking I'll replace both mufflers with some straight pipe and a cherry bomb.

Keep in mind broken exhaust under the car sounds significantly different (louder, tinnier, more resonance) than complete straight pipe to the back.
Also make sure you end with a turndown, both for sound and it keeps the soot off the back of the car, trust me :shock:

I'm in the same boat, in the same city... that makes two AAZs with pothole mufflerectomies in the Port City.
FWIW, it is much louder when it exits under the car; it echoes around. If you get it going straight through & out the back, it is much quieter.

Addautomotive and Infinitrium, I know in NB you have the annual safety inspection, same as in NS, but do your cars pass with no muffler? I want to do the same thing, but after looking into the rules surrounding inspections, the car must have a cat, resonator and a muffler. Just curious how it works in NB.

On the advice of my lawyer, I decline to answer that question.
Hypothetically, if it looked like it had all of those components, but they had been hollowed out, it *could* pass.
just sayin, yo.

:lol:
As for the hollowed out parts, the same hypothetical thought crossed my mind.

Dr. D's jetta had a 2.5" fron the turbo back, mandrel bent without a muffler. Especially when hot, you could clearly hear a very distinctive whistle out the pipe while it idled.

I have a 3'' mandrel bent Turbo back straight pipe on my 1.6l. TD. It's an awesome sound and I can definitely hear the Turbo at idle. On long trips I have to wear some ear plugs though 'cause I realized that I heard a ringing in my ears when I got home. Its not too loud in my opinion but everyone is different. I want to make the cold air intake with a cone filter down into the front there and that should really open it up even more. Right now I can totally notice a difference in performance especially when cruising on the highway. Its only really loud at certain RPM's like when your passing on the highway or hammering the throttle. I love it.
